quirino (codeforces)

We were playing checkers. I used to kid her once in a while because she wouldn't take her kings out of the back row. But I didn't kid her much though. You never wanted to kid Jane too much. I think I really like it best when you can kid the pants off a girl when the opportunity arises, but it's a funny thing. The girls I like best are ones I never feel much like kidding. Sometimes I think they'd like it if you kidded them - in fact I know they would - but it's hard to get started, once you've known them a pretty long time and never kidded them.
